BC Court Order Interest Calculator.
Work out interest owing under British Columbia's Court Order Interest Act — on a single judgment, or on support that came due month by month and was only partly paid. Payments reduce the balance from the day they're made.
Support owing before this date accrues pre-judgment interest; from this date onward, post-judgment interest applies. Leave blank if no order has been made yet.
Usually today, or the date of a proposed payout. Rates are published through Dec 31, 2026.
Pick the date range the support was owed over — each month becomes its own amount owing on its due date, the way a court calculates arrears. Enter the amount per month, or the total for the range and we’ll spread it evenly.
Add each payment on the date it was actually made — whatever the amount. Payments come off the outstanding balance that day, and interest runs on the reduced balance from then on.
